Feature Benefit Bullets

Maximum DC Gate Trigger Current: 150 mA

The high gate trigger current allows for reliable and precise triggering of the SCR, ensuring stable performance in various applications.

Non Repetitive Peak On-state Current: 125 A

The high non-repetitive peak on-state current capability makes this SCR suitable for handling short-duration high current loads without causing damage to the device.

Maximum On-state Current: 10 A

With a maximum on-state current of 10 A, this SCR can effectively handle moderate to high current loads, making it versatile for different power management applications.

Maximum Operating Temperature: 125 °C

The SCR's high maximum operating temperature allows it to operate in harsh environmental conditions without sacrificing performance, increasing its reliability and lifespan.

Trigger Device Type: SCR

Being a Silicon Controlled Rectifier, this product offers precise control over the triggering process, making it suitable for applications requiring accurate power management.

Minimum Operating Temperature: -65 °C

The SCR can operate at very low temperatures, making it suitable for applications in extreme cold environments or industrial settings where temperature fluctuations are common.

Maximum DC Gate Trigger Voltage: 3.7 V

The low gate trigger voltage requirement allows for easy integration with control circuits, providing efficient and reliable triggering of the SCR.

Repetitive Peak Off-state Voltage: 50 V

The SCR's ability to handle repetitive peak off-state voltages up to 50 V ensures stable operation in applications where voltage spikes or fluctuations are common.

Minimum Critical Rate of Rise of Off-state Voltage: 30 V/us

With a minimum critical rate of rise of off-state voltage of 30 V/us, this SCR can effectively handle sudden changes in off-state voltage, protecting the device from potential damage.
